# Step 15 Review S-RBI Analysis and IOW

## ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/Degradation%20Management%20Final%20(6).jpg?sv=2026-02-06&spr=https&st=2026-10-28T12%3A53%3A08Z&se=2026-10-28T13%3A53%3A08Z&sr=c&sp=r&sig=j7WrhZuYnKldblg7sJfbHn6wrqcWd%2FXzIepWLzHZ8aE%3D)

## Aim

Regularly review the [S-RBI Analyses](/v414/docs/risk-based-inspection-rbi-theory) and [IOWs](/v414/docs/integrity-operating-windows-iows-theory) to make sure that the most recent and applicable information is included in the assessment.

This is indicated as an optional step in the cycle, only because it may happen at a frequency that is different to that of the recurring Schedules. It will also sometimes happen at hoc.

See [Methodology Step 15](/v414/docs/methodology-step-15) and [Software Step 15](/v414/docs/software-step-15).
